Please note that IGS’s pin numbering is reverse to industry
standards. VDC and GND are internally connected to the above
‘Power Connector’
Do not use 6 or 4 pin RJ-12/11 connectors as it will cause
permanent damage to the socket.
An 8-pin ribbon cable with an RJ45 push-fit connector or an 8-pin
twisted-pair patch cable with RJ45 may be used. Suitable cables
are obtainable from retailers.
1: +12 V DC nominal (+8 to +27V DC)
2: +12 V DC nominal (+8 to +27V DC)
3: Device supplies + 3V DC
4: GND
5: TX (RS232): only 1 user!
6: RX (RS232): only 1 user!
7: GND
8: GND
Pin 1 Pin 8 (view from rear)
For 8-pin cables pins 1=2 and pins 7=8 should be linked. If the
other wires are not to be used, they should be individually
insulated and may not be soldered together or twisted in pairs.
If the incoming power supply uses the Power/Data
Port connection, special attention must be given to
the instructions given in the chapter in this
handbook entitled Power Supply.
The (typically transparent) plug must be examined to determine
the cable colour coding so the open cable end may be correctly
configured. On patch cables the neighbouring wires of Pins 1/2,
3/4, 5/6 and 7/8 are usually twisted together. Neighbouring wires
are usually of the same colour, though one of the two colours
alternates with white.
